Insights
Very low-birth-weight infants receiving higher fluid intake in early life face increased risk of severe bronchopulmonary dysplasia. Higher fluid intake from days 2-4 is a significant risk factor for developing severe BPD.
Area of Science:
- Neonatal Medicine
- Pediatric Pulmonology
Background:
- Bronchopulmonary dysplasia (BPD) is a significant cause of morbidity in very low-birth-weight infants (VLBWI).
- Early life fluid management is crucial for VLBWI outcomes.
Purpose of the Study:
- To investigate the association between early fluid intake and the severity of bronchopulmonary dysplasia (BPD) in VLBWI.
Main Methods:
- Retrospective chart review of 75 VLBWI (gestational age < 32 weeks, birth weight < 1,500 g).
- Analysis of demographic, clinical data, maternal risk factors, and fluid intake in the first 4 days of life.
Main Results:
- Severe BPD was associated with lower gestational age, lower birth weight, surfactant use, patent ductus arteriosus (PDA), and pulmonary hemorrhage.
- Higher fluid intake from the 2nd to 4th days of life (346.44 ± 42.38 mL/kg) was significantly associated with severe BPD compared to lower intake (323.91 ± 27.62 mL/kg).
- A fluid intake cutoff of 345 mL/kg from days 2-4 was identified as a significant risk factor for severe BPD, even after logistic regression analysis.
Conclusions:
- Higher fluid intake in VLBWI during the 2nd to 4th days of life is a significant risk factor for developing severe BPD.
- This finding highlights the importance of careful fluid management in the early neonatal period for VLBWI.
Objective:
This study aims to investigate the association between fluid intake in the first 4 days of life and the subsequent severity of bronchopulmonary dysplasia (BPD) in very low-birth-weight infants (VLBWI).
Study Design:
A retrospective chart review of 75 infants with a gestational age of less than 32 weeks and a birth weight of < 1,500 g was performed. Demographic, clinical data, associated maternal risk factors, and amount of fluid received in the first 4 days of life were analyzed.
Results:
Severe BPD was associated with a lower gestational age (27.04 ± 2.073 wks vs. 28.70 ± 1.706 wks, p=0.001), lower birth weight (981.44 ± 244.54 vs. 1,199.63 ± 165.39 g, p < 0.001), use of surfactant (91.7 vs. 63%, p=0.002), patent ductus arteriousus (PDA) (70.8 vs. 37%, p=0.004), pulmonary hemorrhage (14.6 vs. 0%, p=0.045), and more fluids received from the 2nd to 4th days of life (346.44 ± 42.38 mL/kg vs. 323.91 ± 27.62 mL/kg, p=0.007). A cut off point of 345 mL/kg of fluids from the 2nd to 4th days of life was selected using receiver operating characteristic curve analysis, and remained a significant risk factor even after multiple logistic regression analysis.
Conclusion:
Our findings demonstrate that VLBWI who received higher fluid intake from the 2nd to 4th days of life are at an increased risk of developing severe BPD.
